All of these automotive dead ends sold in tiny numbers and, as a result, are now pretty much forgotten. In some cases, that’s entirely deserved, as we don’t fancy the Cadillac Cimarron or Sao Penza being revived any time soon. But not all of these cars were dogs – some deserved a better fate. We'll start with cars aimed at the US market, then go on to Europe and finish off with some marvellously obscure British ones.
